Application of two operators transform from class a operator to the class of hyponormal operator

In this article, we give an operator transform (*) from class A operator to the class of hyponormal operators. It is different from the operator transform defined by M. Chō and T. Yamazaki. Then, we show that σ(T)=σ((*)){0} and σa()(*))\{0}, in case T belongs to class A. Next, we obtain some relations between and (*).
